Enwell Energy plc is an independent company involved in the exploration, development, and production of oil and gas resources within Ukraine. The company holds and operates a complete production license for the Mekhedivsko-Golotvshchinske and Svyrydivske gas and condensate fields, situated in the Poltava region. Additionally, it encompasses the Vasyschevskoye field in the Kharkiv region. Enwell also maintains a full interest in and operates the Svystunivsko-Chervonolutskyi exploration license, located in the Poltava region of north-eastern Ukraine. However, as of late 2024 and throughout 2025, operations at its core Mekhedivsko-Golotvshchinske, Svyrydivske, and Vasyschevskoye fields have been suspended due to orders from the Ukrainian authorities, which cite sanctions related to indirect ownership structures. The company is actively pursuing legal challenges against these suspensions, including commencing arbitration proceedings against Ukraine under a bilateral investment treaty to seek monetary damages and the reinstatement of its licenses. Formerly known as Regal Petroleum plc, the company adopted the name Enwell Energy plc in May 2020. Established in 2002, its corporate headquarters are located in London, United Kingdom. Enwell Energy plc operates as a subsidiary of Smart Holding (Cyprus) Limited.
